This invention relates to apparatus for placing fabric over a body, thatis over a wall to be exposed and along the sides thereof. The body willusually be of plastic. The most common use for a device in accord withthe invention, is in a brush for removing lint and small particles fromclothing or fabrics. Forsuch an application, the fabric is one providedwith a slant pile and with the pile filaments all slanted insubstantially the same direction so that brushing a fabric in theadvance direction of the slanted filaments removes particles from thefabric, and brushing a surface acting as a receptacle for the particlesin the reverse direction, removes the particles from the brush. Withsuch an application, the fabric covered body is usually provided with amating cover member, covering all of the fabric holding body except thefabric covered surface in- The invention provides apparatus for applyinga fabric (preferably padded on the non-exposed side) to a fabric holdingmember having a first wall to be covered with fabric and side wallsextending therefrom, and having adjacent the edges of the side walls,remote from'the first wall engagement means for retaining in positionfabric covering the wall intended to be covered and extending along theside walls. Preferably the apparatus also provides means for applyingover said fabric holding member, a cover covering all but the exposedside and preferably assisting in ensuring the retention of the fabric onthe fabric holding member.

The apparatus preferably comprises lips designed to frame thecross-section of the body holding member and to beresiliently biased todefine a smaller aperture. The fabric holding member first wall andfabric in registration therewith are caused by the apparatus to passthrough the lips which are caused to move outwardly by the memberspassing therethrough. Acting under the inward bias, the lips fold thefabric about the edges of the first wall, cause it to lie along thetransverse walls and cause it to engage and be held by the fabricengagin g means on the fabric holding member.

Preferably, the apparatus as described above, also allows the lips tocontract over the fabric holding member and with the fabric thereonholds it until the cover member is applied. The apparatus is designed sothat when the cover member is applied, the lips are spread to allowmating of the cover member with the fabric holding member and are thenmaintained spread until the assembled brush is removed.

I In drawings which illustrate a preferred embodiment of the invention:

FIG. 1 shows the fabric attaching apparatus in the rest position;

FIG. 2a and 2b show stages in the operation of the apparatus inattaching the fabric;

FIG. 3 shows the fabric holding member, with the fabric attachedretained in position;

FIG. 4 shows the arrangement of the apparatus prior to the initiation ofthe application of the cover;

FIG. 5 shows the cover member applied;

FIG. 6 shows the article removed;

FIG. 7 shows an exploded view of the members; and FIG. 8 shows a planview of the fabric shaping members.

As shown in the specific embodiment the device comprises a base 10defining an upwardly facing bore wherein is slidable a platformlZ biasedto the upward position by a compression spring 14 resting at one end ona groove 16 in the platform and at the other end on flanges 18 on thebase. For greater steadiness of the platform there is preferablyprovided a rod 20 like a piston rod extending downwardly from theplatform and through a holein the base member to a recess 22 allowingthe necessary retraction of the rod travelling with platform 12. Aperipheral ledge is provided in the peripheral lower extremity of thebore to limit the downward movement of the platform at the desiredlevel. The bore near its upper end is enlarged to provide a step 24 fora purpose to be hereinafter described.

The shape of the'bore platform, and bore enlargement, in plan view allcorrespond to the shape of the brush to be produced with dimensionaltolerances and clearances required by the operation to be described. Theshape of the brush may vary widely from the ovoid shape shown and stillbe constructed in accord with the inventive apparatus, as hereinafterdiscussed.

A plurality (here 6) of lips 25 each forming a portion of the generalcontour, are inwardly biased by compression springs bearing on thehousing and on the lip members as shown. The lips are provided with anupper surface sloping downwardly and inwardly to an inner edge toprovide a bevel. The lips are designed in their innermost position, asindicated in FIG. 3, to define a closed periphery somewhat smaller thanthat desired for the brush fabric holding member 26, and as retracted,spaces appear between the side edges of adjacent lip members whichincrease as the lips are retracted to their widest spacing. In FIG. 1the lips are retained against their bias by the side wall of platform 12and the spacing of these lips in the intermediate position is such thattheir contour defines the desired shape for the brush although there aregaps as aforesaid. As stated, the contour of the lips is designed to beaccurate attheir intermediate position, as shown in FIG. 1, and it willbe appreciated that for the motion required from this intermediateposition to wider and narrower positions that the number of lipsprovided may be as many as is desirable. It is thought that six lipswill be a preferable number to combine reasonably continuous support forthe fabric with reasonable economy of design, but it will be noted thatas few as four and possibly fewer may be used but four is thought to bethe minimum. A larger number is useful but will increase the expense.

The lips 25 which are designed to ride on the fabric material arepreferably constructed of teflon for low friction and long wearingqualities. The lips in addition to having an innermost position as shownin FIG. 3

have an outermost position, shown in FIG. 6. The

fabric holding member will be designed, as shown, having a first wall30, side walls 32 extending transversely therefrom and preferably, as inthis arrangement, extending perpendicular thereto and a hollow plasticconstruction open atone side, as shown, with four rectilinearly arrangedbosses extending from wall 30 in the same direction as walls 32. Thehead 42 is shaped so that the four bosses may make a friction fittherewith. Here, the head, rectangular in general crosssection, isrecessed at each corner as shown, to make a friction fit with the bossesand releasably retain the fabric holding member in position thereon. Asshown, the bosses 43 are seated on the head and are frictionallyreleasably retained in place by spring loaded balls 44 outwardly biasedby a spring in the center portion of the head. The bosses are providedwith downwardly extending bores 46 for attachment of the cover memberthereto. There is provided for attachment of the fabric, outwardlyextending tines 39 peripherally extending outwardly from adjacent theupperedge of the side walls. The outer contour of the side walls issimilar to that of the bore and designed to be inset therefrom by thethickness of the fabric and any padding material. The side walls 32 ofthe fabric holding member extend away from first wall 30 to edges 37.

As will be noted from FIG. 4, 5 and 6 a cover 50 is provided for thebrush (which brush is comprised of the fabric holding member, fabric andcover). The cover has an upper wall 52 designed to overlie the brushcentral bosseswith pegs 54 designed to be received in the lower memberbores 46 and an outer wall 56 designed to overlie the upper portion ofthe fabric holding member side wall and fabric and to retain the fabricengaged with the tines 39 to firmly sustain it in position.

The fabric 58 is preferably used with padding 60 although the inventionwould operate with fabric alone but the fabric is preferably providedwith an inner padding layer lending a more pleasing contour to thefinished brush as illustrated in FIG. 6.

The fabric 58 with padding 60 attached is cut to a similar shape to thefirst wall 30 of the fabric holding member but is made sufficientlylarger to allow the fabric covering wall 30 to be folded to extend alongside walls 32 and inwardly over edge 37. The upper surring 59 designedto center the fabric over platform 12.

The pile fabric which it is preferred to use as the bristle formingmember with this invention, is produced by nylon filaments woven througha cotton backing to provide an extent between stitch apertures doublethe pile length required.

. These extents or some are then cut to produce the piles, and thesepiles are panned which is the application of the heated surface to thepile in one sense to produce the required slant or slope to producebrushing when moved in one direction, and cleaning when moved in theother direction.

Inter alia this material may be obtained from Collins and AikmanCorporation, Ca-vel Division, Ca-vel, North Carolina 271 12, U.S.A.

The brush formed in this way has the bristles slanting in one direction,i.e., all of the bristle axes are substantially non-normal to thebristle backing surface and are all displaced by such slope inapproximately the same direction from the normal.

In operation, the platform 12 is in the position shown in FIG. 1 and thelips 25 are retained at an intermediate position by the sideedges of theplatform. With the device in this arrangement, the fabric 58 and padding60 are placed over the platform 1 with the fabric in contact therewithand centering means 59 as shown is used to properly center the fabricwhich is designed to centrally provide the area corresponding to thewall 30 of the fabric holding member and to extend 'face of the body ispreferably provided with a guide side walls 32 and be folded inwardlyover the upper edge 37. The head 42 with the fabric holding member 26attached thereto, is moved downwardly into contact and in registrationwith the platform. Downward movement of the three members: fabricholding member 26, fabric 58 and platform 12, slightly retracts the lips25 and as the platform moves downward the lips 25 act under the biasingpressure supplied by their springs 26 to fold and maintain the fabricand padding extending beyond the edges of wall 30 parallel to the sidewalls 32 with the members continuing to move downwardly against theupward bias pressure on the platform 12 (supplied by spring 14) from theposition shown in FIG. 1 (referring to the dotted fabric outline). Asthe lips 25 ride opposite the outwardly extending tines 39 along thefabric they press the fabric and padding over the tines causing thefabric and padding to engage the tines and hence to be retained inposition. wrinkling of the folded fabric is minimized due to thetendency of the padding (preferably of sponge rubber or a spongyplastic) to conform to the stress requirements of the fabric. Thisretention is further increased in the positions shown in FIG. 3, wherethe upper edges 37 of the fabric holding member has moved downwardlypast the plane edges of the inward lips 25 so that the lips 25 undertheir bias have moved inwardly over the fabric holding member to foldthe fabric 58 and padding 60 inwardly thereover. In this position thelips 25 act as shoulders to prevent upward movement of the fabricholding member and the fabric, and the head 42 is withdrawn therefrom,since the frictional retention of the head to the fabric holding memberstill allows withdrawal separation of the two members.

With the fabric holding member held in this position a new head isprovided as illustrated in FIG. 4,

preferably by sliding the fabric holding member head to one side andsliding a head 60 complementary to the shape of the cover member, intoplace.

The mechanism for alternating the two heads over the platform 12 and forproperly positioning the heads are not shown as they form no part ofthis invention, and as many alternative means of performing this will bereadily available to those skilled in the art.

The cover member is manually placed with the edges of its side wallslocated on the chamferred lip walls and the lower ends of pegs 54 in theupper ends of the bores 46.

The head 60 is then caused to move downwardly pressing the cover memberso that the wall edges thereof, bearing on the chamferred surfaces ofthe lips, cause the lips to move backwardly, and, as shown in FIG. 5 theouter walls to bear on the fabric, retaining it in engagement with thetines 39 while telescoping over side walls 32 and while pegs 54frictionally engage in bores 46.

The cover member now securely holds the fabric in place and is securelyattached to the fabric holding member by the posts in the bores and bythe overlapping walls and tines. Moreover the side walls of the covermember retain the lips by their edges in retracted position.

Thus when the head is removed the brush with the platform arises underthe platform biasing spring pressure and the brush may be removed.
